doccheck reports accessibility errors in 52 tables (!) in java.desktop files. See attached log.

Although these errors have been reported for a long time in the low-level doccheck reports, they have not been included in the high level reports, until now.

In general, the majority of the errors seem to be the lack of row headings on tables, which is typically achieved by adding `scope="row"` to the cells in a column in which the content of each cell is unique and can be regarded as defining the row.


Update:
In addition, there are two tables in the comments for Path2D.Float#writeObject and Path2D.Double#writeObject that need to be updated in the same way. Although the methods are private, and don't show up in the main java.desktop API files, the methods do show up in the serialized-form.html file. (See attachment "accessibility.log")
